Description

FIELD OF THE INVENTION

[0001] This invention relates to a modular structure for temporary exhibitions of the type comprising at least one shaft component.

DESCRIPTION OF PRIOR ART

[0002] As it is known, various structures currently exist for making stands at fairs and the like.

[0003] More specifically, various structures exist that are made of a series of modular plates that can be assembled. These plates can then be fastened to the ground through joining methods or appropriate plinths.

[0004] These components can be assembled at will to create a stand for exhibitions in fairs or for other similar temporary exhibitions. They are made from polymer materials or cardboard or something similar.

[0005] The prior art described above has some considerable drawbacks.

[0006] Assembling structures for temporary exhibitions becomes a slow and laborious process.

[0007] Another drawback arises from the fact these structures can be quite inconvenient to transport.

[0008] There are also difficulties resulting from the presence of electrical connections for lighting and the equipment displayed on the stand. It is in fact quite difficult to keep these electrical connections contained within the structures and they can constitute a hazard for people visiting or passing by the stand.

[0009] No less inconvenient is the fact that these structures are costly and have to be changed for each demonstration or fair.

SUMMARY OF THE INVENTION

[0010] In this context, the technical aim underlying this invention is to devise a modular structure for temporary exhibitions that would largely help to overcome said drawbacks.

[0011] Given this technical aim, one of the main purposes of the invention is to create a modular structure for temporary exhibitions that will be quick to assemble. Another aim of the invention is to create a simple, cheap and versatile modular structure for temporary exhibitions.

[0012] The invention also aims to create a modular structure for temporary exhibitions that will allow electrical cables to be arranged in such a way so as not to be a hazard for visitors, passers-by and attendants.

[0013] No less important is the invention's aim to create a modular structure for temporary exhibitions that will be easy to transport.

[0014] The technical aim and the aims specified are achieved by a modular structure for temporary exhibitions as claimed in the appended Claim 1.

[0015] Preferred embodiments are specified in the dependent claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] With reference to the Figures, the modular structure according to the invention is generally referred by number 1.

[0018] In summary, this comprises at least one shaft component 2, at least one sheet 3 with at least one fixed end 3a, fastened to the shaft component 2, and at least one free end 3b broadly opposite the fixed end 3a.

[0019] In particular, the shaft component 2 contains an internal cavity 2a and is in effect a hollow prismatic strip 4, preferably shaped as a cylinder or quadrangle, with diameter between 5 and 25 cm and with wall thickness of between 0.5 and 3,0.

[0020] The strip 4 should be made from metal but could also be from polymer materials.

[0021] The shaft component 2 comprises two end sections 5 level with the bases of the prismatic strip 4.

[0022] The end sections 5 also include a joining mechanism 5a, which can allow the ends 5 to be joined to a finishing component 13 such as a plinth 13a in stone, metal or another material.

[0023] The said joining mechanism 5a is best made from a joint, as shown in Fig. 3. The shaft component 2 also includes rolling means 6 for the sheet 3.

[0024] In particular, the rolling means 6 is able to roll the sheet 3 inside of the prismatic strip 4.

[0025] To this end, the rolling means 6 is made up of a bar or central shaft 7 with an axle 7a, which largely coincides with the axle of the shaft component 2, to which the fixed end 3a of the sheet 3 is fastened.

[0026] The central shaft 7 will ideally be fastened to the end sections 5 by two rotating pivots 8 having the axle 7a as the rotational axle.

[0027] The rolling means 6 also includes and elastic return mechanism 9 able to exert angular momentum on that shaft 7 in the direction in which sheet 3 rolls so as to keep sheet 3 rolled up.

[0028] The elastic return mechanism 9 is best made from a spring placed level with one or both of the ends 5.

[0029] The prismatic strip 4 also includes a slot 10 to allow sheet 3 to pass from the inside to the outside of the strip 4

[0030] The structure 1 also includes a releasable fastening means 11 from the free end 3b to the shaft component 2.

[0031] This will ideally be contained in the sheet 3 or in the shaft component 2.

[0032] In particular, it consists of a rigid slat 12 bound to the free end 3b comprising some hooked latches 11a that can be inserted into the appropriate slots 11b located on the prismatic strip 4 and fastened to the walls of the strip, as shown in Fig. 3.

[0033] The slat 12 also functions as a block level with slot 10. It is thicker than the width of the slot 10 and prevents sheet 3 from completely entering the prism 4. The modular structure 1 should ideally also include at least one crossbeam 14. This crossbeam 14 is able to join the finishing components 13 of two or more shaft components 2 and includes latching means to the shaft components 2, which are also best made from a mobile fastener or something similar. Furthermore, the crossbeam 14 can be pre-joined to at least one finishing component 13 and latch directly on to the joining mechanism 5a of an end section 5.

[0034] The crossbeam 14 should also be of length equal to or less than the length of the sheet 3 in the direction of the crossbeam. Consequently the sheet 3, pulls out from a shaft component 2 linked to a second shaft component 2 by means of the crossbeam 14 and can be latched on by the releasable fastener on said second shaft component 2.

[0035] The crossbeam 14 could also comprise a releasable fastener that could be linked to sheet 3.

[0036] A variety of shapes and sizes for crossbeams 14 and shaft components 2 could be imagined, and in particular some shaft components 2 could contain more than one sheet 3.

[0037] Also, every shaft component 2 contains a variety of releasable fasteners 11 which can hold in a series of membranes 3.

[0038] The structure 1 also includes electrical connections 15 along the shaft components 2 and said crossbeams 14.

[0039] The electrical connections 15 comprise an electrical link to an outside system or to the mains and ideally one or more sockets, which can be linked up and provide electricity to lights, computers and various equipment. The sockets are best placed level with the finishing components 13, the plinths 13a and the like. In particular the connections 15 include electrical cables 17 which it is best to place within, and along the whole length of the shaft components 2 and the crossbeams 14.

[0040] In particular, the cables 17 can be placed inside the central shaft 7 rather than bound to it.

[0041] The electrical connections also include some mobile connection components 18 level with the joining mechanism 5a and the latching mechanism.

[0042] These mobile connections 18 are made up of conductive metal joints or simple conductive metal plates connected to the electrical cables.

[0043] The structure 1 can also contain latch supports, which could for example be made up of the slots 11 b or other components that can allow plates 20 or leaflet holders, etc to be latched on perpendicular to the shaft components 2. The latch supports are also able to latch one end of a crossbeam 14.

[0044] Figs. 6a, 6b, 7a and 7b demonstrate specific implementations of the rigid slat 12 and its attachment to the sheet 3.

[0045] In particular, the rigid slat 12 can be attached to the sheet 3 by elastic fastenings 21, pre-arranged in the desired numbers and preferably level with the upper and lower ends of the sheet 3 level with the free end 3a.

[0046] The elastic fastenings 21 serve to compensate for any possible slight irregularities in position or shape in the shaft components 2 and the sheet 3, thus keeping the sheet 3 perfectly taut and free from folds or creases on its surface.

[0047] In Figs. 6a and 6b the elastic fastenings 21 are made from elastic strips 21a, with one side stuck or sewn onto the sheet 3, and the other rolled, for example using by a ring on the end, around a small bar 22 which protrudes from the rigid slat 12, held on by fastenings 22a.

[0048] In order to make it easy to house and assemble the elastic fastenings 21, the rigid slat 12 should preferably be in the form of a box fixed by two semi-monocoques 12a which can be detached by bolts 12b, as demonstrated in Fig. 6b.

[0049] Figs. 7a and 7b demonstrate that the elastic fastenings 21 can also be made from stay-rods 21 b .

[0050] These are made from an elastic thread 23 or, as in the diagrams, from non-elastic thread attached to a spring.

[0051] Each thread 23 is stretched between a point of attachment 24a located on the sheet 3 and a rolling spool 24b supported by the rigid slat 12 and which can be fixed as desired for example by fastening a bolt in a place chosen at the time. This allows a choice of the optimum tension to keep it stable.

[0052] Also, it is best if between the point of attachment 24a and the rolling spool 24b there is a return wheel 24c, which will allow the stay-rods 21 b to be positioned in a manner that is more convenient and less of a hindrance.

[0053] In particular, the stay-rods 21 b make it possible to make the sheet 3 either move towards the inside of the rigid slat 12, in order to avoid any localised creases, or to be moved higher or lower.

[0054] For example, it is possible to raise the sheet 3 by tightening a stay-rod 21 b placed near the upper edge of the sheet 3, as shown in Fig. 7b, and at the same time slightly slackening a stay-rod 21 b placed near the lower edge of the same sheet.

[0055] Fig. 8 finally shows that it is also possible to make it easy to prearrange various types of sheets 3 by dividing them into several sections that can each be moved independently.

[0056] The sheet 3 can be arranged into at least 3 parts: a first part 25a attached to the inside of the shaft component 2, a second part 25b attached to a rigid slat 12 and at least a third part 25c stretching between the first two and which can be detached from them.

[0057] Detaching said sections of the sheet 3 is done through by release buttons 26 or other equivalent devices, such as zips, velcro, hooks, etc.

[0058] A modular structure 1 according to this invention operates as follows.

[0059] The shaft components 2 are positioned along a suitable perimeter so as to allow the structure 1 to be assembled.

[0060] They are attached to the floor by plinths 13a, which can be connected to the end sections 5 or to the floor with appropriate screw-in or other types of connections and suitable end sections 13 but still connected to the shaft component 2.

[0061] The shaft components 2 are linked to one another with crossbeams 14, which make the structure 1 rigid and solid.

[0062] Then, as shown in Fig. 4 the membranes 3, positioned within the shaft components 2, are linked to an adjacent shaft component 2 by appropriate means of releasable fastening 11.

[0063] Through the steps described, and connecting only one part of the apparatus 1 with an electrical network or the like, the electrical connections 15 described above can also be created and the sockets in the structure 1 will become live. Electric lights and other equipment can therefore be linked up to them. Appropriate plates 20 can then also be joined to the shaft components 2 to create tables or leaflet holders, amongst other things.

[0064] The invention achieves considerable advantages.

[0065] The structure 1 can be assembled quickly and with ease. It is very quick and easy to join the shaft components 2 to the crossbeams 11.

[0066] A further advantage of the structure 1 is that it is very versatile and can therefore be used for many purposes.

[0067] Another advantage of the structure 1 is that it contains its own electrical connections 15 without these constituting a hazard or creating problems in assembly.

[0068] No lesser advantage of the structure 1 is the ease with which it can be transported. It is in fact composed almost entirely of easily transportable bars. The invention is susceptible to modifications and variants falling within the inventive concept. In particular, the electrical connections might be able to carry information, for example by using a telephone cable or internet connection, etc. The shaft components 2 can also have removable upper expansions to increase the height of the structure.

[0069] Between the finishing components 13 fixed by the plinths 13a, bars can be placed through which will pass the electrical supply cables for the equipment displayed inside of the space defined by the structure according to the invention.
